System of equations?

Y=2x+y And 3x+y=16 System Of Equations?

Answers

Answer 1

Answer:

Good day sir

The answer is (3,7)

Step-by-step explanation:

One way is to graph the line

Another way is to do it the hard way

3x + y = 16 is y = -3x + 16

Add the original equations up and solve

2y = -x + 17

This is a start (just solve this equation) but the answer is (3,7)

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)

Answers

Answer:

y = -2/3x + 8/3a

Step-by-step explanation:

Given points

(a, 2a) and (-5a, 6a)

Slope-intercept form

y = mx + b

Slope of the line is

m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

The y-intercept is:

2a = -2/3*a + bb = 2a + 2/3ab= 8/3a

So the line is:

y = -2/3x + 8/3a

Answer:

y = -2/3 - 8/3a

Step-by-step explanation:

Find the slope using [ y2-y1/x2-x1 ]

6a-2a/-5a-a

4a/-6a

-2/3

Find the y-intercept.

y = mx + b

y = -2/3x + b

2a = -2/3(a) + b

-8/3a = b

y = -2/3 - 8/3a

Mai uses Triangle A and says the slope of this line is 6/4.
Elena uses Triangle B and says no, the slope of this line is 1.5.
Do you agree with either of them? Explain.

Answers

yes. the slope is 1.5 so we agree with both of them because 6/4=1.5 and 1.5/1=1.5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. Yes i can agree with both of their statements.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

As we know that the slope of a line will be always same on a given line. If slope triangle A has slope 6/4. Then triangle B will be also have the same slope.

As both triangles are connected to the same line. These two triangles A and B  will have same slopes.

Mai uses Triangle A and says the slope of this line is 6/4.

If we convert fraction 6/4 to decimal we get 1.5 value.

So i agree with both of their statements.

What is the unitary method?The unitary technique entails finding the value by multiplying the single value and then solving the problem using the initial value of a single unit. If an event may take place in m different ways and a second event can take place in n different ways after it, then the two events that follow can take place in m n different ways.

Given,

time spend for homework is

4/5 hours = 4/5×60 = 0.8×60 = 48 minutes

if 1/2 of this time is spent on working science homework

48×1/2= 48×0.5= 24 minutes

Hence, the total minutes spent, working on science homework is 24 minutes.
